Getting Started in 2013, Part #18, A look ahead

Builders,

There is a look at the next five group topics in the new numbering system. The Head Group (1500) is the last expensive component of building a long block. The other groups here are mostly made of parts that came with your core engine and basic labor you can add yourself. Getting through groups 1000-1900 will give you an engine that is internally complete, and it is the lion’s share of the money spent building the engine

Later groups address oil systems, starters, ignitions, etc, all external systems that are bolted on your long block. All of this can be purchased as you go, adjusted on your own timeline and budget.  The later parts are intentionally broken down into affordable blocks that can be installed at one time, like the $516 starter system group (2400).

About William Wynne
I have been continuously building, testing and flying Corvair engines since 1989. Information, parts and components that we developed and tested are now flying on several hundred Corvair powered aircraft. I earned a Bachelor of Science in Professional Aeronautics and an A&P license from Embry-Riddle Aeronautical University, and have a proven 20 year track record of effectively teaching homebuilders how to create and fly their own Corvair powered planes. Much of this is chronicled at www.FlyCorvair.com and in more than 50 magazine articles.
